Benefits of technology

[0010]With the benefit of the present invention there is provided a method to avoid reading the entirety of a very large data file, and to rapidly produce a display of all or part of the data without losing key characteristics of the data, such as peaks.
[0012]Also, the present invention can provide a faster method of calculating various statistical data requested by a user viewing the data, for all or part of the data, once the data has been displayed.

Problems solved by technology

This creates a problem when handling the resultant data files using the kind of computers typically available in offices, e.g. for the analysis of industrial or scientific measurements, as even though personal computers have also increased in speed and capability, they cannot yet process whole recording files, now in the order of gigabytes, in real time as expected by the user.
In the future computers will undoubtedly have an increased amount of solid-state memory and more processing power, but if the size of the data files keeps increasing at the same rate as personal computer capabilities increase, then this problem will remain.

Embodiment Construction

[0023]The data are typically time-varying values of a measured physical quantity such as temperature, position, speed, concentration or light intensity. Thus their values are likely, in applications envisaged for this invention, to vary continuously as a function of time. However, even values with significant discontinuities can be used.

[0024]The preferred embodiment of the present invention provides a data acquisition system designed to receive an analogue signal, sample the signal at a predetermined sampling rate and record the sampled data to a raw data file. The user of the system can set up custom measurement protocols to record this data based on their measurement needs. At the same time as recording this data, the system calculates a statistical summary for blocks of raw data of a predetermined size and stores this statistical data such that it is associated with the raw data file of samples taken from the signal. The data considered useful by the end user can then be stored ...

Abstract

A method of providing a display signal, wherein digital data to be displayed has associated with it statistical values determined for pre-determined sized blocks of the digital data, comprising the steps of: determining display scaling parameters; determining from the display scaling parameters the extent to which the statistical values are suitable to use in place of some or all of the digital data when determining which data points of either the digital data and / or statistical values to display; determining the data points to display; reading the digital data and / or statistical values to be displayed; and generating the display signal from the digital data and / or statistical values.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to United Kingdom Patent Application Serial No. 0500089.8 filed Jan. 5, 2005 entitled, STATISTICAL STREAMING, the disclosure of which is incorporated by reference in its entirety.FIELD OF THE PRESENT INVENTION[0002]This invention relates to the field of data recording for display and analysis. Particularly, but not exclusively, the invention relates to increasing the speed at which a computer can display a user selection of recorded data samples from a recorded data file and increasing the speed at which a computer can compute and display relevant statistics for that selection of recorded data, especially when dealing with extremely large data files.BACKGROUND TO THE PRESENT INVENTION[0003]In the data acquisition and storage industry, it is common for large amounts of data to be recorded. The amount of data stored is increasing rapidly. The capacity of computer storage, such as hard disks, is increasing ac...
